 SIG-TFN (Time and Frequency Network) Quantum aims at providing a forum for the community working around Time and Frequency distribution quantum technologies, including quantum networking, computing, sensing, cryptography and communication across Research and Education Networks. It will gather and exchange experiences, ideas and knowledge on the development, deployment, testing and standardisation of Time and Frequency quantum solutions, leading to the development of a Core-Time and Frequency Network (C-TFN)coherent quantum strategy across GEANT and the evaluation and testing of suitable quantum technologies. The SIG has will have an advisory role to GEANT GPPC and relevant project management/coordination function.

 Aims:

  1. To provide a forum for gathering and exchanging experiences, ideas and knowledge on the development, deployment, testing and standardisation of
Time and Frequency distribution
  1. quantum technologies across R&E networks, with a particular focus on
interoperability;
  1. quantum computing, networking, communication, cryptography and sensing.

    This will be achieved through group meetings (online and face-to-face), the use of online collaborative tools, collating and dissemination of information or organising pilot projects;

  2. To define agreed objectives and commitment levels related to the operation and management of
a Time and Frequency Network;
To define an agreed data management plan and having a common repository for information and data;
  1. quantum-based devices and protocols;

  2. To
To create a federated access to repositories and data;
To
  1. make recommendations and play the role of a technical adviser. 
   


Running period:

This is the first year of operation of the SIG-TFNQuantum, which was established in February 20242025.

Objectives

  • Investigate a path to sustainability of the CLONETS-DS C-TFN, both for GÉANT and for participating NRENs and NMIs.
  • Carry out cost modelling to identify the extent of the future funding needs for fibre and flywheels.
  • Shepard funding through governance of GN5-2.
    • Engage EURAMET, NRENs, GÉANT and the European Commission to find solutions to long-term funding.

    Objectives

    • Expand on the CLONETS-DS architecture and integrate lessons learnt from PTB-PSNC pathfinder.
    • Investigate if tiers of flywheel performance are needed e.g NMI flywheel, NREN flywheel, etc.
    • Prepare a C-TFN architecture.
    • Prepare a technical specification for the C-TFN flywheels.
    • Prepare a technical specification for the GÉANT cross-border fibre links.
